I have yet to see some one NOT offer to let you shoot their gun just by saying "hey, what kinda gun are you shooting?"Go to the range offer to pay for ammo if you can shoot their rifles. shoot many...Then you can make an informed decision. ANY well maintained rifle in almost any caliber will serve you well.
op didn't ask about shotguns he asked about rifle recommendations!<>
Given all modern considerations, the .308 is hard to beat for all around.
In Texas, a .243 can do just about anything a .270 can; if you need more there are magnums.
Remember some Western Mountain States mandate .30 cal or better for large animals like elk, even if that seems silly.
If we have a collapse of society, ammo will be everyone’s critical concern and there is more .308 already exsting plus being made than everything except 5.55/.223 & .22LR.
But do you have a good SHOTGUN ?
Good Luck !

A suppressed .22. Then an M1 GarandI am looking for a general purpose rifle. (If there is such a thing). I already have an ar15 and a bolt action in 556. I don't know much about rifles so be gentle. Without breaking the bank.
Thanks
